4 Claims.

Our present invention relates generally to woven fabric, and has particular reference to ornamental fabrics of the dotted Swiss variety.

It is a general object of our invention to provide a woven fabric in which an ornamentation composed of dots or spots is produced in a novel and more economical manner.

One customary way, heretofore, of producing an ornamental spot on a plain-woven ground fabric is to employ four rovings or picks interwoven with a series of adjacent warp threads, so that the exposed portions of the rovings define a substantially circular area. This produces what is known in the trade as a four-pick dot. Ornamental spots formed of only two rovings or picks have also been attempted, but as a general rule theyare unsatisfactory because they pull out too easily.

In accordance with our present invention, a substantially equilateral spot of ornamentation is produced upon a plain-woven ground by the employment of only two rovings, yet the rovings are of such a character and size and are held down in such a manner that the disadvantages heretofore encountered with ordinary two-pick dots are entirely avoided. As a result, we are enabled to produce a fabric of the dotted Swiss variety, which is in every respect substantially equivalent, in appearance and strength, to the ordinary fabric having four-pick dots. manufacture of the present fabric is, however, far more economical.

One of the features of our invention lies in the employment of a pair of rovings, each of which has a thickness or width which is approximately one-half of the length or width of the spot that is to be produced. Thus, where the fabric is made of cotton, we employ so-called six-hank rovings, whereas ordinary practice has heretofore resorted to twelve-hank rovings.

We achieve the foregoing objects, and such other objectsas may hereinafter appear or be pointed out, in the manner illustratively ex-' emplified in theaccompanying drawing, wherein- Figure 1 is a plan view of a fragment of an ornamental fabric of the present character;

Figure 2 is a plan view of the region surrounding one dot, this view being greatly enlarged;

Figure 3 is a cross-sectional view taken substantially along the line 3-3 of Figure 2;

Figure 4 is a cross-sectional view taken substantially along the line 4-4 of Figure 2.

The ground fabric is of a plain-weave, and we have applied the reference numeral ID to the The ground wefts and the reference numeral H to the warp threads. In producing the present spot, we interpose between two adjacent ground wefts the two rovings l2 and i3 which are arranged side by side; and, in accordance with our invention, they engage with six adjacent warps wherever a spot is to be formed on the surface of the fabric. In Figure 2, for example, it will be observed that the rovings l2 and I3 engage with the warp threads I l-I9 inclusive. The outermost warps,

- designated by the reference numerals l4 and I9,

pass over both rovings and thereby delimit the spot of ornamentation. Beyond these lines, the rovings float on the rear of the fabric, as will be understood by those skilled in the art, until the region of the next spot is reached. In the finished fabric it is usually customary to shear off the rovings on the back of the fabric, so that only the portions defining the spots are left. It is a spot of this shorn character which is illustrated in Figures 2-4.

It will be observed that the penultimate warps l5 and I8 pass under both rovings. These warp threads tend to push the rovings upwardly on the face of the fabric. The innermost warps l6 and I1 weave over and under the rovings in alternate relation, and serve to tie the rovings down. It will be observed that the warp thread l6 passes over the roving l2 and under the roving l3; whereas the warp thread I! passes under the roving l2 and over the roving l3.

In accordance with our invention, each of the rovings l2 and I3 is composed of a piece of yarn which has a thickness or width approximately one-half of the length which is exposed between the outermost warps l4, and I9. ,Where the fabric is composed of cotton, a so-called six-hank roving, or its equivalent, is adequate. The spot produced is substantially equilateral, and to the ordinary observer it creates the same impression as the conventional four-pick not which has heretofore been customarily employed for a fabric of the present type.

The manner in which the exposed portions of the rovings are positioned upwardly on the face of the fabric is shown most clearly in Figures 3 and 4; and these figures, together with Figure 2, clearly depict the manner in which the rovings are firmly held in interwoven relationship to the ground fabric. There is no tendency toward, nor likelihood of, loosening the rovings. Each ornamental spot is, therefore, firmly and staunchly held in position.

While the invention is admirably adapted for use in connection. with plain-woven fabrics of the lawn or ,voile type, nevertheless it will be understood that the invention has equal applicability to other types of fabrics, including those employing fancy weaves such as dobbies and jacquards. Accordingly, where the term plainweave ground" is used herein and in the appended claims, it is intended to refer only to the ground fabric immediately surrounding each dot or spot of ornamentation.

The present ornamentation can be applied to fabrics composed of various types of ground threads, e. g., mixtures of cotton and rayon yarns or spun rayon yarns, rayon twisted or untwisted yarns, acetate twisted or untwisted yarns, and/or linen yarns. Similarly, the rovings can be made of either white or dyed material, of spun rayon, whether dyed, grey, or bleached, and/or of spun acetate material. The latter type of roving would be advantageous for cross-die purposes.

In general, it will be understood that changes in the details, herein described and illustrated for the purpose of explaining the nature of our invention, may be made by those skilled in the art without departing from the spirit and scope of the invention as expressed in the appended claims. It is, therefore, intended that these details be interpreted as illustrative, and not in a limiting sense.

Having thus described our invention, and illustrated its use, what we claim as new and desire to secure by Letters Patent is 1. An ornamental woven fabric having a plainweave ground and a figure thereon composed of dots, each dot being formed by only two rovings arranged side by side between a pair of adjacent ground wefts, said rovingsengaging with six adjacent warps, the outermost warps passing over both rovings to delimit the spot, the penultimate warps passing under both rovings to push them upwardly on the face of the fabric, and the innermost warps weaving over and under said rovings in alternate relation to tie the rovings down.

2. An ornamental woven fabric as set forth in claim 1, in which each roving is of sufiicient cross-sectional area, with respect to the length which is exposed between said outermost warps, so that the exposed portions of the two rovings will conjointly cover a substantially equilateral area.

3. An ornamental woven fabric as set forth in claim 1, in which each roving has a width approximately half of the length which is exposed between said outermost warps.

i. An ornamental woven cotton fabric of the voile or lawn type, having a plain-weave ground and a figure thereon composed of dots, each dot being formed by only two approximately six-hank cotton rovings arranged side by side between a pair of adjacent ground weftasaid rovings engaging with six adjacent warps, the outermost warps passing over both rovings to delimit the spot, the penultimate warps passing under both rovines to push them upwardly on the face of the fabric, and the innermost warps weaving over and under said rovings in alternate relation to tie the rovings down.
